T() ALL WIIOM I'I MAY- CONCERN:

Be it known that we, J; FORCE and G'. W. RENWICK, of Elgin, in thecounty of Kane, and Stato of Illinois, have invented a new and usefulImprovement in 'lenter-Bars for Drying Cloth; and we do hereby declarethat the following `is a fulland exact description thereof', referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making a part o f this specification, in which- Figure 1is a vertical longitudinal section.

'Figure 2 is a vertical transverse section of the same.

Similar letters of reference, where they occur in the separate gurcs,denote like'y parts in both of the drawings. v

In the manufacturing of cloth it is found that when drying the same itwill contract laterally, thus leaving the piece irregular in width anduneven in thickness. To ovcrcom-c this diculty, the cloth must betightly strained upon a frame or bars, and dried while in that position.Our invention is designed for this purpose, and its nature consists inso arranging or constructing the frame or bars that a piece of cloth ofany given number of yards may be evenly stretched laterally its entirelength by simply turning a single crank.

'To enable others` skilled in the art to construct and use ourinvention, we will proceed to describe ithe same with reference to thedrawings.

and m" represent the standards or posts of the frame, which are firmlyattached to the building, or may be mortised into sills or foot-pieces,which lie upon the ground when used in the open air. H and H representthe bars, to which the cloth is attached. Bar II is firmly boltedorotherwisc attached t'o the lower part of `posts m and m. Bar H/isprovided at its ends with friction-wheels tand t, which move in verticalgrooves and i at 'the top and inner sides of the posts; the centre ofsaid, bar, being held in position by means of straps of iron, S, movingin vertical slots, T and T, out -longitudinally in the top orjupper partof the centro standards n and n of the frame. e e represent a series ofvertical levers, which are `hinged or jointed to bars H and II", andpass at oblique angles to the' centre between the bars, and are thereconnected one to the other by means of a second hinge or joint, B,arranged as shown in the drawings. These joints each receive ahorizontal rod, L, which passes from one series or set of levers to theother the entirolength of the frame, thus connecting each set; 'alsoconnecting with screw N, to which the crankv C is attached by means of aswivel, E. The operation of our device is as follows: The edges of theclothare attached to the barsv I-I and H by means of a series of hooks,as shown on lines e c. Crank- C' is then rotated, which moves levers e eto avertical position by means of rods L and screw N, ,thus adjustingor, raising bar II to the proper height, which evenly strains the cloththe entire length of the piece, and is left in that position untilentirely dry, I-Iaving thus described the nature and object of ourinvention, what we claim as new, and by Letters Patent, is-v Thecombination of bars II and I-I, frictionfwheels t and t, screw N, rod L,a'nd levers e e, substantially as and for the purpose described. i

In testimony whereof We have signed our names before two subscribingwitnesses.
